Herremans sustained the injury in the first quarter of Monday's 28-13 loss to
the New Orleans Saints.

The loss of Herremans is the latest setback for an offensive line which has
been crippled by injuries this year after starting left tackle Jason Peters
ruptured his Achilles in the offseason and starting center Jason Kelce tore
the anterior cruciate ligament in his right knee in Week 2.

The eight-year veteran, who the club selected in the fourth round of the 2005
NFL Draft, made his 100th start in Monday's loss and has not missed a game
since the 2009 season.
